Pengaruh Masa Simpan terhadap Kualitas Fisik dan Kadar Air pada Wafer Limbah Pertanian Berbasis Wortel

The aim of this research is to find 1) the changes of physicalquality andwater content on wafer of agricultural waste were kept in a range of different times; 2)the most effective time for savingsan wafer of agricultural waste. The research was conducted in September-November 2014 in Banjar Baru Villages, Sukau Subdistrict, West Lampung and in the Laboratory of Nutrition and Feed Livestock, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung.This research used Completely Randomized Design (CRD) with four treatments by saving the wafer for 0 week, 2 weeks, 4 weeks, and 6 weeks with fourrepetition. Data were analyzed with Analysis of Varians and continued with Least Significant Difference Test (LSD) 0,01 or 0,05.The result of this research showed that wafer with differential storage time had a signifficantly effect (P<0,01) on the water level, texture, and scent on wafer of agricultural waste. The average of water content on wafer of agricultural waste based on carrot after saved by six weeks in the amount of 42,23 %, so there was no best saving time of wafer agricultural waste based on carrot because the water content of the wafer exceeds the standard of water content of the feed material to be saved that is 14%.

Pengaruh Berbagai Komposisi Limbah Pertanian terhadap Kadar Air, Abu, dan Serat Kasar pada Wafer

This experiment aims to know water content, ash, and crude fiber of wafer of various agricultural as feed and to know the best water content, ash, and crude fiber from wafer of various composition of agricutural waste. This experiment was held Juny-July 2014 in Bandar Baru Village Sukau Subdistrick West Lampung Regency. This sample were analyzed in the Laboratory of Animal Nutrition and Feed Science, Department of Animal Husbandry, Lampung University. The experimental design used in this research was Completely Randomized Design (CRD) with three treatments and four replications. The treatments were : A: sweet potato 8% + potato 3% + leaf couliflower 5% + China cabbage 10% + carrot 50% + chayote 5% + tomato 15,99 % + molasses 3% + salt 0,01%; B: sweet potato 15% + potato 5% + leaf couliflower 10% + China cabbage 15% + carrot 40% + chayote 6% + tomato 5,99 % + molasses 3% + salt 0,01%; C: sweet potato 20% + potato 7% + leaf couliflower 15% + China cabbage 20% + carrot 23% + chayote 8% + tomato 3,99 % + molasses 3% + salt 0,01%. The data were analyzed by using variance analysis with significant level of 5% and or 1%, and will be followed by the Least Significant Difference test (LSD). The results of this study showed that the composition of wafer with various agricultural wastes was not significant effect (P> 0.05) on water content, but significantly (P <0.05) of the crude fiber content and highly significant (P <0.01) against of the ash content. The best treatment on the wafer with various agricultural waste composition is wafer C

Pengaruh Penambahan Berbagai Starter pada Pembuatan Silase Ransum terhadap Kadar Serat Kasar, Lemak Kasar, Kadar Air, dan Bahan Ekstrak tanpa Nitrogen Silase

The aim of this research are to find: 1) the effects of addition of various kind levels of starter to crude fiber, crude fat, moisture content, extract material without nitrogen, in silage feed, 2) one of the best starter in increasing the nutrient content in silage feed. The research was conducted in December 2014 – Februari 2015 at Department of Animal Husbandry, Faculty of Agriculture, University of Lampung and in the Laboratory of Nutrition and Feed Livestock, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The number of microbes was analyzed in Balai Veteriner Lampung. The method in this research used completely randomized design. The treatments was consisted of basal ration (R0), basal diet + stater EM4 (R1), basal diet + EM4 starter culture (R2), and the basal diet + starter rumen fluid (R3). The results showed that the addition of various kind levels of starter indicated significant effect (P0.05) to crude fiber and BETN of silage.

Efektivitas Penggunaan Arang Kayu dan Batok Kelapa sebagai Penghambat Kerusakan Fisik dan Kimia pada Dedak pada Selama Proses Penyimpanan 8 Minggu

Rice bran is a side product of the rice mill in producing rice. Rice bran is the part of rice husk thatis generated from the rice bleaching process. This feed is a material that would become fragile oreasily damage if it is kept beyond a certain time. The oil content that is relatively high makes ricebran not durable because oil is easily hydrolyzed so that make it rancid due lipase contained inrice. Prevention of feed damage during storage can be done by providing materials containingcertain active substances that can prevent damage. Charcoal gives a solution to prevent damageduring storage because of feed ingredients are hygroscopic and porous, which can absorb water upto the point of balance. The purpose of this study was to determine the effect of the use of woodcharcoal and coconut shell charcoal to physical and chemical damage of rice bran during 8 weeksperiod of storage. The experimental method that was used in this study is completely randomizeddesign CRD with 3 treatments and 4 replications. The use of coconut shell charcoal is better inmaintaining the rice bran odor, reducing the decrease of fat levels and minimizing the increase ofperoxide when compared to administration of charcoal wood

Pengaruh Penambahan Berbagai Starter pada Pembuatan Silase terhadap Kualitas Fisik dan Ph Silase Ransum Berbasis Limbah Pertanian

Objective of the research was to study the effect of using starter on silage making. Four treatments with 3 replications were applied in a completely randomized design. The treatments were R0 = Basal diet; R1 = R0 + EM-4 4%; R2 = R0 + enriched EM-4 4%; and R3 = R0 + rumen fluid 4%. Results of the experiment showed that EM-4, enriched EM-4, and rumen fluid significantly affect the color, texture, pH, as well as the smell of the silage. The best quality of silage was achieved by using EM-4 4% and using rumen fluid 4% as starter in silage making

Identifikasi Kualitas Dedak yang Disimpam dalam Berbagai Jenis Kemasan

Rice bran is by product from rice milling and feed is one that is difficult to dry so provision when stored in large quantities with special packaging. Information about packaging materials has not been known. The purpose of this study was to determine the quality of bran that is stored in various types of packaging and determine the best packaging in storage. This study used completely randomized design followed by Least Significant Difference test. The variables measured were organoleptic and chemical testing. The results showed that a various packaging used in storage of rice bran for 6 weeks was significantly effect (P0,05) to colour, odor, and the rate of fat rice bran. In addition, position sampling in packaging for 6 weeks were not significantly effect (P>0,05) to colour and the texture, but was significantly effect (P<0,05) to odor of rice bran. Then white plastic packaging as the best in maintaining the quality of rice bran
